Ep.23 “The Female Titan”

Why did the Female Titan let Armin off the hook?

Q, Armin, who hides his face with a hood, is attacked by a female titan and falls off his horse.
Armin was prepared for his death, but for some reason, the female titan confirmed his face and left without killing him.
In vol.6 ep.23 “The Female Titan” (anime 1st ep.17).

A, The true identity of the female titan was Annie. Perhaps she couldn’t kill Armin because she had some feelings for him.
However, well… Is it as a friend? As a person in love? I wonder…
If it was an unnamed character he might have been killed.

Reiner was told that Eren was on the right wing.

Q, Before the operation began, Reiner was told that Eren was on the right wing. And it was in the same direction that the female titan appeared.
However, Jean was told it was the rear left flank.
What do they mean…
In vol.6 ep.23 “The Female Titan” (anime 1st ep.17).

A, Commander Erwin suspected that there was an enemy spy in the corps, and in order to expose the enemy, he did not tell everyone where Eren really was.
That means, It suggests that Reiner, who Eren thought was on her right wing, and the female titan that appeared from the right wing, are comrades of the enemy.
In vol.10 ep.42 “Warrior” (anime 2nd ep.6).

Why did the female titan change direction to the central rear?

Q, Jean, Reiner, and Armin fight the female titan, but Reiner is grabbed by her with her high athletic performance.
Reiner manages to escape by cutting its finger with a snap blade just before it is nearly crushed.
After that, the female titan stared at its own hand for a while, then for some reason changed direction to the center rear where Eren was and ran away.
In vol.6 ep.23 “The Female Titan” (anime 1st ep.17).

A, Perhaps, when Reiner was captured by the female titan, he probably wrote something like “rear center” or something on the palm of its hand with his own blade, conveying information about where Eren is.
In vol.10 ep.42 “Warrior” (anime 2nd ep.6).

Krista is liked by horses.

Q, When Armin and others were in need of two horses, Krista came and brought with Jean’s two horses he had strayed off.
How could she have conveniently done that?
In vol.6 ep.24 “The Titan Forest” (anime 1st ep.18).

A, When Krista was a kid, she had no friends, but her only friends were the horses and other animals she took care of on the ranch. That’s why she can communicate with animals.
